ch.maxant.rules.Engine

ch.maxant.rules.Java8Engine

public class Java8Engine
extends Engine

This class supports Java 8 Streams being used with the engine. //to use a lambda, construct a SamAction and pass it a lambda. IAction action1 = new SamAction("outcome1", i -> new BigDecimal("100.0")); IAction action2 = new SamAction("outcome2", i -> new BigDecimal("101.0")); List> actions = Arrays.asList(action1, action2); Engine e = new Engine(rules, true); See Engine for more details.
